Abstract
A motor assembly with an integrated cooling system is provided in which a coolant (e.g., oil) is injected into a hollow region of the rotor shaft. The coolant is expelled out of the rotor shaft and into the motor enclosure via multiple thru-holes, thereby allowing efficient cooling of both the stator and the rotor assemblies.
